During a coastal flood event, the City will deploy this flood barrier to help protect the northern part of the Fort Point neighborhood. This effort is part of a citywide coastal flood resilience plan.
The deployable portion consists of two removable posts and several aluminum stop logs. The permanent components are two concrete pillars blended into the existing landscape and a concrete pad onto which the stop logs clamp down during a flood event. When deployed, the stop logs span the width of the walkway beneath the pedestrian bridge and stand approximately 4 feet tall. During that time, the Harborwalk will remain accessible from the Children's Museum and the entrance beneath the Seaport Boulevard Bridge.
The tidal trigger for deploying the flood barrier is 14.4’ (MLLW), as reported by NOAA. The mayor can approve deployment. This happens after a recommendation from the City’s Office of Emergency Management. Then, the flood barrier posts will be set up, and the deployment team will add panels as needed.
The Planning Department is managing the project's design and construction in collaboration with:
- the Office of Climate Resilience, and
- the Parks and Recreation Department.
Temporary construction of the infrastructure that supports the deployable is set for March to May 2026. There will be minimal impacts to the landscape during construction. All impacted features will be restored or enhanced.
